OCXO (Oven Controlled Crystal Oscillators) +5.0 V; +12 V
OC11E Series
50 ohm Load Sine Wave
Mercury OC11E is 25.4x25.4 mm 5 pin solder sealed metal pacakge
with 19.0x19.0 mm pin-to-pin spacing high stability low aging OCXO.
Besides standard AT cut crystal, users can also choose SC cut crystal
for better performance. HCMOS square wave output is available as OC11T series.
